Title: An improved process and device for obtaining a highly porous cellular light material from blast furnace slag and similar fused materials
IPC: C21B3/06
Filed: 1930-03-07
Abstract: 350,526. Treating slags. SCHOL, C. H., Allendorf, Dillkreis, Germany. March 7, 1930, No. 7501. Convention date, Jan. 23. [Class 22.] Blast furnace slag or similar fused material is treated to obtain a highly porous, cellular, light, dry product by passing the molten slag into a trough through which water or other liquid is flowing, part of the trough having a downwardly curved formation so that in this part the inclination increases as the force and amount of the water diminishes. Slag passes from a furnace d down a fireproof channel e into a trough a having a very short straight part and a downwardly curved part f. Below the mouth of the channel e is a fireproof inclined plane b, which may be water cooled, on to which the molten slag falls. Water or other liquid is passed into the trough a either above or beneath the inclined plane b. The porous mass is moved along the straight part of the trough a by the liquid and then falls down the part f under gravity into a pit g from which it is removed by an elevator c to breaking and sorting devices. The curved part of the trough is continued inwardly from the point at which the porous mass falls to remove any water which may be at the bottom of the trough and the pit g has a perforated bottom through which water drains to a sump h from which it is recovered by a pump k and pipe l.
Patent GB-401701-A (GB)
Title: Improvements in and relating to protective systems for electric distribution systems
IPC: H02H7/26
Filed: 1932-03-14
Abstract: 401,701. Protective cut-out arrangements. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 14, 1932, No. 7572. Convention date, March 12, 1931. [Class 38 (v).] In a sectional protective arrangement of the type provided with energy-directional relays at the ends of the section which trip the circuitbreakers with faults within the section, the contacts of the energy-directional relays are mechanically latched in their open position by relays which are responsive to the characteristics of a short-circuit, such relay at at least one end of the section being responsive to a decrease in voltage. As shown in Fig. 1 the energy-directional relays 2 have their contacts 10 spring-biassed to the closed position but normally held in the open position by latches 11 under the control of relays 7, which are responsive only to excessive drop in voltage at the points A B. When this condition occurs the contacts 6 of the relays 7 are released so removing the latches from the contacts 10. These contacts are then free to close under the control of the energy-directional windings 3, 5 and if the fault is within the section both energy-directional relays close and a tripping circuit is completed from a battery 12 through trip coils 13 and a pilot wire 14. Indicators 15 are provided to indicate the closing of the directional relays, and if only one of these relays closes, as for example if the fault is beyond the protected section, the relatively high resistance of the other indicator 15 in series with the affected trip coil 13 prevents a sufficient current flowing in this coil from the battery 12 to produce tripping of the corresponding circuit-breaker although the increased current in the indicator coil at the other end of the section would produce an indication there of the tripping of the other circuit-breaker. The indicators would also indicate the blowing of the fuses in the circuit of the potential transformers 8. In a modification (Fig. 2, not shown) the under-voltage relay 7 is replaced by an excess-current relay at the end of the section from which power is transmitted. Alternatively under-impedance relays may be employed. Instead of the pilot wire 14 between the ends of the section known forms of wired wireless communication of the relay positions between the ends of the section may be employed, (Fig. 3 not shown).

Abstract: 469,839. Master control of motors. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. March 13, 1936, No. 7625. [Class 38 (iii)] A series-parallel control system comprises a master controller MC associated and mechanically interlocked with two separate reversing switches MR1, MR2, so that a reversing switch can be operated only when the master controller is in its off position, and the master controller can be effective only when a reversing switch is in an operative position, In addition when a first reversing switch MR1, used when a motor is cut out, is operated, the master controller cannot be moved to effect transition to parallel connections and a motor cut-out switch is provided having interlock contacts MCO which are in series with contacts 34, 35 of the second reversing switch MR2 controlling the control current for the motor switching means, and these interlock contacts are opened when a motor is cut out. The reversing switches may be interlocked so that only one can be placed in an operative position at a time. A single key is used to operate the cut-out switch and the reversing switches and can be removed from the latter only when they are in a neutral position. The invention is described for a tramcar equipment employing two motors controlled by armature resistances and field diverting resistances, and with a power brake switch. The cut-out switch may be combined with the reverser or the power brake switch and the reverser MR2 may have a more prominent position than the reverser MR1.
